MERCERIZING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 734,333, dated. July 21, 1903.

Application led May 12. 1900.

To a/ZZ whom t may concern:

Be it known that I, PAUL J EANMAIRE, residing at Mlhausen, Alsace, inthe Empire jof Germany, have invented certain new and useful Improvements in Mercerizing Apparatus, of which the following is aspecification. This invention relates to improvements in an apparatus for mercerizing textile fabrics; and the object of the invention is to provide means for stretching the fabric after the same has been impregnated with the mercerizing fiuid, so that the fabric becomes of greater width than when it left the bath and a silklike gloss is imparted to the goods, while the fabric remains of the same or approximately the same length.

For this purpose the invention consists in i the combination, in a mercerizing apparatus, of a plurality of laterally-acting card-clothed eXtensor-rolls located to operate in succession upon the impregnated fabric; and the invention consists, further, in the combination with these rolls, arrangedas stated, of setting-rolls and of means for washing the fabric.

In the accompanying drawings, Figure 1 is a diagram indicating the various rolls and vats of an apparatus embodying my invention. Fig. 2 is a diagram illustrating another form of apparatus embodying my invention, and Fig. 3 is a side view of one of the card! clothed extensor-rolls.

Referring to Fig. 1, a indicates the fabric, and lo k the extensor-rolls, of which two are shown arranged so as to act in succession upon the impregnated fabric. Three rolls care employed in this construction, arranged, respectively, before the first extensor-roll, between the first and second, and after the second.

These rolls are preferably provided with roughened surfaces-card-clothed, for instance-so that the fabric Whenupon the .same cannot shrink, but retains its size. This causes the fabric to set to more or less extent, depending on the speed of the rolls, kind of In other words, the fabric does not shrink `after passing o one of these rolls, or if it shrinks at all then to a less degree than were it not passed `in contact with the setting-roll. In order to render this setting action more effective by increasing the time of application to the s etting-roll, these rolls are preferably made of Serial No 16,464. (No model.)

very'much larger size than the extenso r-rolls lc, as shown. The'extensor-rolls are provided with card-clothing, so as to firmly engage the fabric for the lateral stretching, the cardtensor-roll, over the third setting-roll, andthence over rolls g in the. sulfuric-acid bath h. Spray-pipes d are arranged below the second extensor-roll and spray the stretched fabric with water for Washing the same simultaneously with the stretching action, the spray from the lower pipe ol passing at one side of the upper pipe. This Washing during the stretching action facilitates thestretching operation, causes a silk-like gloss upon the iinished goods, and yreduces the tendency to shrinkage, so that when the fabric leaves the last setting-roll it has very little, if any, tendency to shrink, and that is removed by -the vneutralization in the acid-bath h of any portions of the mercerizing fluid remaining in the goods. After passing the bath hthe goods may be again Washed and then dried or subjected to any other suitable well-known treatment. p

In Fig. 2, Z indicates a roll' o f fabric which has already been impregnated. ct indicates the fabric upon and passing from this roll successively over the .extensor-rolls k lc 7c, which are in this case arranged in unbroken succession, each receiving the fabric directly from the .preceding roll and stretching it to greater Width, the fabric thereby undergoing three lateral stretchings. From thelast extensor-roll 7c it passes upon the setting-roll c,

upon which it is washed by spray-pipes d d,

arranged in proximit'yvto` the roll. Thence it passes over the rolls g in the acid-bath for iinal neutralization. The goods may thereafter be subjected to anysuitable finishing treatment. The successive extensor-rolls are each located so as to receive and act upon the fabric before the same has opportunity to IOO shrink or to shrink to any marked extent from thedimensions to which it was stretched bythe precedingroll. Bythismeansanintermittent stretching, each time to a greater width, is accomplished with a shorter o1 longer period of rest for the fabric between each stretching, according to whether the fabric is fed directly from one eXtensor-roll to the next, as shown in Fig. 2, or passes over intermediate setting-rolls, as in Fig. l. By these intermittent stretchings, with a period of rest between each stretching, the width of the fabric may be increased from ten to fifteen per cent. in the case of cotton cloth. The surface of the setting-rolls may be smooth instead of card-clothed. In this case, however, they do not act as setting-rolls, but merely serve as conveying-rolls between the eXtensor-rolls,alfording asurface for the cloth to pass over during the period between the intermittent stretchings.

I am aware that rollers of the card-clothing are well known, and, on the other hand, that they are as heretofore used of no utility for producing a very great enlargment of the fabric and have never been employed, therefore, but to maintain the fabric at its original dimensions and prevent the shrinkage of its form. That whichI claim as my invention is the location of the card-clothing, not upon a roller, but upon a determined part of `the surface of the bars of the usual spreading-roller. By these novel means I render the spreading-1'ollers capable of producing the effect of extension which is absolutely impossible to be obtained without the same.`

The placing of card-clothing upon rollers is common, but the adaptation of the cards to the spreading-rollers, as set forth, has never been accomplished with success before now.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a mercerizing apparatus, the combination of a mercerizing-bath, and a laterallyacting card-clothed eXtensor-roll, the cardclothing being located at the outer ends of the bars of said roll, and the portions of said bars between said outer ends being smooth, substantially as set forth.

2. In a mercerizing apparatus, the combination of a plurality of laterally-actingr cardclothed eXtensor-rolls located to act in succession intermittently upon the impregnated fabric, the card-clothing being located at the outer ends of the bars of said rolls, and the portions of said bars between said outer ends being smooth, substantially as set forth.

3. In a mercerizing apparatus, the combination of a plurality of laterally-acting cardclothed eXtensor-rolls located t0 act in succession intermittently upon the impregnated fabric, the card-clothing being located at the outer ends of the bars of said rolls, and the portions of said bars between said outer ends being smooth, and means for washing the fabric simultaneously with the stretching of the same on the last roll, substantially as set forth.

4:. In a mercerizing apparatus, the combination of a plurality of lateral1yacting cardclothed extensor-rolls located to act in succession intermittently upon the impregnated fabric, the card-clothing being located at the outer ends of the bars of said rolls, and the portions of said bars between said outer ends being smooth, means for washing the fabric simultaneously with thestretching of the same on thelast roll, and a setting-roll located to receive the fabric from the last extensor-roll, substantially as set forth.

In a mercerzing apparatus, the combination of a plurality of laterally-acting cardclothed eXtensor-rolls located to act in succession intermittently upon the impregnated fabric, the card-clothing being located at the outer ends of the bars of said rolls, and the portions of said bars between said outer ends being smooth, means for washing the fabric simultaneously with thestretchingofthesame on the last roll,a setting-roll located to receive the fabric from the last eXtensor-roll, and a setting-roll between said last eXtensor-roll and the preceding roll, substantially as set forth.

6. In a mercerizing apparatus, the combination of a mercerizing-bath, a setting-roll, an eXtensor-roll located between said bath and setting-roll, said eXtensor-roll being provided at the outer ends of its bars with cardclothing,and the portions of said bars between the outer ends being smooth, and means between said eXtensor-roll and setting-roll for washing the fabric, substantially as set forth.

7. In a mercerizing apparatus, the combination of a mercerizing-bath, a setting-roll, a plurality of eXtensor-rolls located between said bath and setting-roll, said extensor-rolls being provided at the outer ends of their bars with card-clothing, and the portions of said bars between said outer ends being smooth, each eXtensor-roll adapted to receive the fabric in wider condition than the preceding roll, and means for directing, a washing liquid upon the stretched fabric passing over said rolls, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
